Understanding Your Grade Calculation at Age 13

To find out your grade, you need to calculate the percentage of questions you answered correctly. Here's how to do it step by step:

1. Identify the total points: You have a total of 40 points.
2. Identify the points you earned: You got 31 correct answers.
3. Calculate the percentage: Use the formula:
   Percentage = (Correct Answers / Total Points) × 100
   So, in your case:
   Percentage = (31 / 40) × 100
4. Calculate:
   First, divide 31 by 40, which gives you 0.775.
   Next, multiply 0.775 by 100, which equals 77.5.
5. Final grade: This means your grade is 77.5%.

So, your overall grade based on the scores is 77.5%. Depending on the grading scale used by your school, this might correspond to a letter grade (like a C or C+). Always check with your teacher for exact grading details!
